onionoo

Been having a devil fo a time keeping my bridge up this week. One question: With the bridge up & running, & the map showing it connecting to circuits, why is onionoo reporting "running":false, ? Should I worry about this discrepancy? Thanks, eliaz

Analysis of log file
by Carsten Larsen 02 Sep '13

02 Sep '13

Hi tor-relay list, I have been running a tor node for 133 days and Im starting to receive some weird messages in the log file. One of them look like this: Received http status code 504 ("Gateway Time-out") from server '154.35.32.5:80' while fetching "/tor/server/d/9169637E422C216BECD05C6CFE3AE..... I also have another one which appear regular: [warn] {NET} Failing because we have 991 connections already. Please raise your ulimit -n. First question is: any ideas how to get ride of these messages ? Second: Would it be possible to submit a log file for further analysis, and to whom should I send it ? The node is running on ARM debian box. I can of cause provide details if it necessary. Best regards Carsten Larsen Fingerprint: E1EE4FB010F28E55B7ACA2D046AB89F3B413F2A3

A bit more evidence on circuit creation storms
by Gordon Morehouse 02 Sep '13

02 Sep '13

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 So, I started having "tubes clogged" problems this evening and realized, finally, that my Raspberry Pi powered relay had been weathering a circuit creation storm since about 18:11 my time. tl;dr main dev-related questions at bottom Aug 29 18:11:03.000 [warn] Your computer is too slow to handle this many circuit creation requests! Please consider using the MaxAdvertisedBandwidth config option or choosing a more restricted exit policy.

Please consider using the MaxAdvertisedBandwidth config option or choosing a more restricted exit policy. [2692 similar message(s) suppressed in last 60 seconds] First off, I'm happy to note that the Pi is far, FAR more able to weather these storms running 0.2.4.x, even without the perfectly optimal OpenSSL (all jokes aside about that particular combination of three words)... Secondly, the number of messages escalated. Here is the worst: Aug 29 18:38:04.000 [warn] Your computer is too slow to handle this many circuit creation requests! Please consider using the MaxAdvertisedBandwidth config option or choosing a more restricted exit policy. [18258 similar message(s) suppressed in last 60 seconds] What on earth is causing so many circuit creation requests in such a short timespan? Again, a Pi-specific note - on 0.2.3.x, the Pi would have crashed or Tor been killed before this number ever reached five digits, so 0.2.4.x is better! I has a metric! However, note that whatever is going on starts plugging up the works in Tor itself: Aug 29 18:18:36.000 [notice] Tried for 129 seconds to get a connection to [scrubbed]:993. Giving up.

Resetting timeout to 60s after 18 timeouts and 172 buildtimes. I assure you, my network connection speed didn't change. I still don't know how in the Tor protocol a circuit creation request is made, but maybe it was them gobbling bandwidth. Probably not, though? There was an increase in average TX/RX bandwidth during this incident, but not to levels that are in any way out of the ordinary for how I use my Internet connection. However, it's still causing trouble with my router (which is running Tomato). Check this out: Aug 29 18:56:14.000 [warn] Your computer is too slow to handle this many circuit creation requests!

Is it DNS requests? Is it TCP connection state entries? It's not bandwidth, we observed that above, and my router can handle far faster pipes than the one it's on currently. The DNS failing is a sign that the router is under severe stress. Back in the 0.2.3.x days, I often had to reboot the *router* after one of these storms, not just the Tor relay. And again - do we really know what is causing this? Something seems seriously wrong with the kind of numbers I'm seeing coming in to a node with MaxAdvertisedBandwidth 250KB. I think a bug should be opened about this, if there isn't one already.

I feel like you are SO missing the point. Making Tor block morally horrible things does not involve telling exit notes to block traffic to known porn sites. The porn sites with the boobies that someone might hit on port 80 on the public internet represent the Catholic Church of porn, metaphorically-speaking. The truly terrible stuff is hidden to where you as an exit node operator would never be able to simply block it by IP address or domain name. It seems clear that it would require designing into Tor the ability to inspect the content of its packets in the unencrypted form, plus be able to be configured to identify and reject files with certain identifiable signatures. This capability would have to be implemented in all nodes, in order to detect the reject-files should they come from the .onion sites. That kind of capability would damage Tor's anonymity at the technical level (</understate>). If someone believes that making a G-rated Tor is a good idea, they must not be considering the wisdom behind why it was designed the way it was, with each node not knowing the nature of the data it passes. The same technical characteristics which protect the investigators and whistleblowers and "rights of humanity" will also by their nature protect the boobie-watchers. Think about this, understand this. It is not about the concept of anonymity and privacy, it's about the technical requirements necessary to provide it in the face of the hostile environment we have now.

That tool is claiming this about our relay: "This IP is infected with, or is NATting for a machine infected with s_ddos_dirtjumper". Says the problem connection was an attempt to connect to port 80 on a "s_ddos_dirtjumper Command and Control server with contents unique to s_ddos_dirtjumper". Behavior last seen 14 hours ago. Read a little about it - wondering if it requires a malicious Tor user to cause a machine to make this kind of traffic flow through Tor, or if an infected victim using Tor would be enough. Seems exit node operators may be able to stop this particular thing if they knew the IP addresses of the described botnet "Command and Control Domains". One could drop that traffic outbound by IP. The abuseat.org site only seems to know its honeypot/sinkhole address though and that's not the one to block.
